Radiation warning signs posted on the exterior of radiation facilities become faded and discolored with time. There are various types of commercially available laminating films for protecting signs from ultraviolet light. We examined the protection effect of polyvinyl chloride (PVC), acrylic resin and fluororesin films applied to the surface of radiation warning signs. The laminated signs were exposed to direct sunlight on the wall of an air filter chamber of a radiation facility for 1200 days. Simultaneously, another set of laminated signs was exposed to light from a xenon-arc weatherometer for 1200 hours. After exposure, the colors on the surface of each sign were evaluated digitally by using a spectrum colorimeter. The results indicated that lamination with a film that blocks ultraviolet light is effective for protecting the signs from fading and discoloration. For long-term protection under direct sunlight, PVC was the most effective among the three materials tested.
